CLAIM OF PRIORITY

This application claims priority under 35 USC § 119(e) to U.S. PatentApplication Ser. No. 61/806,526, filed on Mar. 29, 2013, the entirecontents of which are hereby incorporated by reference.

TECHNICAL FIELD

The invention relates generally to a system and method for wirelesslydocking an automated external defibrillator (AED).

BACKGROUND

Sudden health problems such as sudden cardiac arrest and injuries causedby accidents kill thousands of people and cause permanent injury everyyear. Fast and competent care to resuscitate such victims of theseproblems can be essential to positive outcomes in such situations. Forexample, it is said that the chance of surviving a sudden cardiac arrestfalls by ten percent for every minute of delay in providing effectivetreatment.

Resuscitation treatments for patients suffering from cardiac arrestgenerally include clearing and opening the patient's airway, providingrescue breathing for the patient, and applying chest compressions toprovide blood flow to the victim's heart, brain, and other vital organs.If the patient has a shockable heart rhythm (ventricular fibrillation orpulseless ventricular tachycardia), resuscitation also may includedefibrillation therapy using an AED, for example. Along with suchaction, an electrocardiogram (ECG) signal for the patient may beelectronically captured, displayed, and monitored, so that rescuers candetermine when the patient's heart has returned to normal or near-normaloperation, and determine when the heart exhibits a shockable rhythm.About half of patients who suffer ventricular fibrillation (VF) have arecurrence of VF within minutes of successful VF conversion, which maythen require reconversion. Patient odds of survival fall with repeatedVF recurrence during resuscitation.

Survivability of a cardiac arrest patient may often depend on theavailability of an AED in good working condition. Like any sophisticatedelectronic device, an AED requires periodic servicing to ensure it willbe ready and available in the event of an emergency. Prompt AEDservicing may depend on the length of time it takes to determine when anAED requires servicing, the type of servicing that is required andscheduling of personnel to provide the service for the AED.

In some embodiments, wireless dock 220 may automatically detect by usingQi-compliant wireless power technology whether interface module 105coupled with AED 110 is within range to communicate with and/or supplypower to interface module 105. If wireless dock 220 is not within rangeof the interface module 105, for example, AED 110 including interfacemodule 105 is not inside the AED cabinet 212 or located on the mountinghook 205, wireless dock 220 may record a time and date that the attemptto communicate with or provide power to interface module 105 occurred.If the wireless dock 220 is within range of interface module 105, theprocessor and memory of the wireless dock may be configured to cause theremovable interface module 105 to power-on by wirelessly transmitting apower-on or wake-up command to interface module 105.

In some embodiments, if AED 110 including interface module 105 arewithin range of wireless dock 220 and wireless dock 105 detects thatinterface module 105 has sufficient power, wireless dock 220 mayperiodically request and receive status information from interfacemodule 105 related to AED 110. One or more requests for statusinformation by wireless dock 220 may be transmitted wirelessly byinterface module 105 to wireless dock 220 using a low-power radiotransceiver, for example, using transmitter 266 packaged as atransceiver in an integrated circuit and received by receiver 236 ofinterface module 105 also packaged as a transceiver. Interface module105 may receive the request and respond by transmitting statusinformation wirelessly to wireless dock 220. Requests for statusinformation from wireless dock 220 to interface module 105 may occurperiodically, for example, daily, weekly or monthly.

Wireless dock 220 may transmit status information received frominterface 105 to a data center or management station, via the Internetfor example, when requested or periodically. In some embodiments,wireless dock 220 may have continuous connectivity with a data center ormanagement station. In some embodiments, data center or a managementstation may send a request to one or more wireless docks includingwireless dock 220, to send status information relating to AED 110. Whenwireless dock 220 receives the request for AED status information,wireless dock 220 may respond by sending AED status informationincluding data/time information and/or AED location information.

At 420, the status information is transmitted through a networkinginterface such as networking interface 282 of the wireless dock 220. Forexample, wireless dock 220 may transmit status information received frominterface module 105 to a data center or management station via theInternet when requested or periodically. In some embodiments, wirelessdock 220 may have continuous connectivity with a data center ormanagement station.

If desired, the different functions discussed herein may be performed ina different order and/or concurrently with each other. Furthermore, ifdesired, one or more of the above-described functions may be optional ormay be combined.

Although various aspects of the invention are set out in the independentclaims, other aspects of the invention comprise other combinations offeatures from the described embodiments and/or the dependent claims withthe features of the independent claims, and not solely the combinationsexplicitly set out in the claims.

It is also noted herein that while the above describes exampleembodiments of the invention, these descriptions should not be viewed ina limiting sense. Rather, there are several variations and modificationswhich may be made without departing from the scope of the presentinvention as defined in the appended claims.
